However, these existing systems often have limitations in terms of efficiency, reliability, and maintenance. In particular, some systems may suffer from excessive energy consumption, unstable temperature control, and potential for failure.

[0005] This necessitates improvements in heat pumps, which require new technologies and design elements.Technical solutions are needed to improve the performance of heat pumps in terms of improved heat transfer efficiency, stability and reliability, energy efficiency, ease of maintenance, etc.

[0042] Figure 1 is a perspective view of a heat pump according to an embodiment of the present invention. Figure 2 is a cross-sectional view of the heat pump shown in Figure 1. Referring to Figures 1 and 2, a heat pump (S) according to an embodiment of the present invention can include a power unit (1) and a housing (3).

[0043] The power unit (1) can be configured to provide a rotational driving force for circulating the liquid and to heat the liquid by applying power to it. That is, the power unit (1) can generate a rotational force by applying power to it, and can circulate the liquid via the rotational force.

[0044] In addition, the power unit (1) can heat the liquid by applying different polarities to one part of the overall structure and the other part. The power source applied to the power unit (1) is a normal AC power source, and can be alternately switched between negative and positive single polarity power sources. In other words, polarity can mean (+) polarity and (-) polarity.

[0045] The housing (3) has a space formed therein, and the power unit (1) can be placed therein. That is, the housing (3) can be configured so that a liquid flows in, is heated by the power unit (1), and is discharged to the outside.

[0046] Conventionally, a heat generating device and a circulation device were installed separately, but in the heat pump (S) according to one embodiment of the present invention, the power unit (1) generates heat and circulates simultaneously, thereby maximizing the efficiency of space utilization, and the heated liquid circulates quickly, improving the heat circulation speed.

[0047] Meanwhile, the housing (3) can be provided so that power can be applied thereto. That is, power supplies of different polarities can be applied to the housing (3) and the power unit (1), and the liquid flowing therein can be heated by the polarity difference between the housing (3) and the power unit (1). That is, the housing (3) can be supplied with power of the opposite polarity to at least a portion of the power unit (1), thereby heating the liquid flowing therein. Specifically, when the housing (3) and the power unit (1) come into contact with the liquid flowing inside the housing (3), heat may be generated in the liquid between the inner surface of the housing (3) and the power unit (1), to which the opposite polarity is applied.

[0048] In addition, the liquid can be heated quickly and uniformly through the wide area of ​​the housing 3 and the power unit 1. Furthermore, the materials of the housing 3 and the power unit 1 can be highly conductive so that an electric current can flow. For example, the housing 3 can be a conductor based on at least one of aluminum, copper, iron, and tungsten.

[0049] The housing 3 may be made of a material with high optical transparency so that the interior can be seen even when current is flowing. For example, the housing 3 may be made of a transparent electrode containing at least one of ITO, glass, aluminum, and carbon. This allows the user to visually check the interior of the housing 3 and identify whether the components housed therein are operating or not, or if there is an abnormality.

[0050] Furthermore, the housing 3 and the power unit 1 may be constructed with a mixture of materials. For example, the housing 3 and the power unit 1 may be constructed with a mixture of conductors and non-conductors. Therefore, the heat pump S according to one embodiment of the present invention may be constructed so that only the conductive portions of the housing 3 and the power unit 1 are electrically conductive when power is applied. In other words, the housing 3 and the power unit 1 are constructed with certain regions divided into conductors and non-conductors, thereby making it possible to adjust the location and degree of heat generation. However, the materials of the housing 3 and the power unit 1 are not limited to these.

[0051] The power unit 1 may include a motor 11, a shaft 13, and a rotating body 15. The motor 11 may generate a rotational driving force. The shaft 13 may be connected to the motor 11 to transmit power thereto. That is, the shaft 13 may be connected to the motor 11 and rotatably provided.

[0052] The rotors 15 may be rotatably mounted in a plurality of units spaced apart from one another on the shaft 13. That is, the rotors 15 may be mounted in a plurality of units spaced apart from one another on the shaft 13. In other words, by providing the rotors 15 in a plurality of units spaced apart from one another, the contact area with the liquid flowing inside the housing 3 is maximized, promoting the circulation of the liquid and maximizing the heating and heat circulation efficiency.

[0053] In addition, a first polarity or a second polarity different from the first polarity may be applied to each of the plurality of rotating bodies (15). As a result, heat is generated by the polarity difference between the plurality of rotating bodies (15), and the liquid can be heated. In other words, the plurality of rotating bodies (15) generate heat, and the heat generated by rotation can be efficiently transferred to the liquid.

[0054] Specifically, the rotating body 15 may include a first impeller 15a and a second impeller 15b. The first impeller 15a may be coupled to the shaft 13 and may have a first polarity applied thereto. The second impeller 15b may be spaced apart from the first impeller 15a on the shaft 13 and may have a second polarity different from the first polarity applied thereto. If the first polarity is anode, the second polarity may be cathode, and if the first polarity is cathode, the second polarity may be anode.

[0055] On the other hand, the shafts (13) may be provided in a multi-stage structure. That is, a plurality of shafts (13) may be arranged in a multi-stage structure corresponding to the number of rotors (15). For example, when two first impellers (15a) and two second impellers (15b) are provided, four shafts (13) are provided, forming a four-stage structure.

[0056] Specifically, the shaft (13) may include a first shaft (131), a second shaft (133), a third shaft (135), and a fourth shaft (137). The first shaft (131) is disposed at the innermost position and has the longest length, and the first impeller (15a) may be coupled to one end of the first shaft (131). The second shaft (133) encases the first shaft (131), is shorter than the first shaft (131), and may have the second impeller (15b) coupled to one end of the second shaft (133). The third shaft (135) encases the second shaft (133), is shorter than the second shaft (133), and may have the first impeller (15a) coupled to one end of the second shaft (133). The fourth shaft (137) encases the third shaft (135), is shorter than the third shaft (135), and may have the second impeller (15b) coupled to one end of the fourth shaft (137).

[0057] The first shaft 131, the second shaft 133, the third shaft 135, and the fourth shaft 137 rotate independently, and the first impeller 15a and the second impeller 15b rotate independently, and polarities can be applied independently to the first impeller 15a and the second impeller 15b. That is, the first impeller 15a connected to the first shaft 131 may be applied with a first polarity or a second polarity via the motor 11 and the first shaft 131. The second impeller 15b connected to the second shaft 133 may be applied with a first polarity or a second polarity via the motor 11 and the second shaft 133. The first impeller 15a coupled to the third shaft 135 may have a first polarity or a second polarity applied thereto via the motor 11 and the third shaft 135. The second impeller 15b coupled to the fourth shaft 137 may have a first polarity or a second polarity applied thereto via the motor 11 and the fourth shaft 137.

[0058] Specifically, a plurality of first impellers (15a) may be provided on the shaft (13) at intervals, and a plurality of second impellers (15b) may be provided and disposed between the plurality of first impellers (15a). That is, the first impellers (15a) and the second impellers (15b) may be disposed alternately along the longitudinal direction of the shaft (13). This allows the first impellers (15a) and the second impellers (15b) to heat the liquid more efficiently and adjust the degree of heat circulation more effectively depending on the polarity applied thereto.

[0059] The first impeller (15a) rotates independently of the second impeller (15b), and when the first impeller (15a) rotates in a first direction, the second impeller (15b) rotates in the first direction or a second direction different from the first direction, or can be stationary. The first direction may be clockwise and the second direction may be counterclockwise. Alternatively, the first direction may be counterclockwise and the second direction may be clockwise.

[0060] Specifically, when the first impeller (15a) rotates in a first direction, the second impeller (15b) can rotate in the first direction. When the first impeller (15a) rotates in the first direction, the second impeller (15b) can rotate in a second direction. When the first impeller (15a) rotates in the first direction, the second impeller (15b) can stop rotating.

[0061] Furthermore, when the second impeller (15b) rotates in the first direction, the first impeller (15a) can rotate in the first direction. When the second impeller (15b) rotates in the first direction, the first impeller (15a) can rotate in the second direction. Furthermore, when the second impeller (15b) rotates in the first direction, the first impeller (15a) can stop rotating.

[0062] That is, the rotation directions of the first impeller (15a) and the second impeller (15b) can be set in various ways, taking into consideration the amount of liquid flowing, the speed of the liquid being supplied, the rotation speed of the first impeller (15a), and the rotation speed of the second impeller (15b), etc. This allows for precise adjustment of the degree of heating of the liquid flowing inside the housing (3) and the circulation speed of the liquid.

[0063] Meanwhile, the housing 3 may include a housing main body 31, a housing rear portion 32, and a housing front portion 33. The housing main body 31 may be configured to encase the power unit 1. That is, the housing main body 31 is configured in a hollow cylindrical shape, the power unit 1 is disposed inside, and liquid can flow inside.

[0064] The housing rear portion 32 is disposed rearward of the housing body portion 31 and communicates the interior and exterior of the housing body portion 31, allowing liquid to flow in. Specifically, the housing rear portion 32 may include a housing rear main body portion 321, a housing rear through-hole 322, and a housing rear extension portion 323.

[0065] The housing rear body part 321 is coupled to the rear of the housing body part 31 and can close the rear surface of the housing body part 31. The housing rear through-hole 322 is formed through the center of the housing rear body part 321 and can allow liquid to flow into the housing body part 31.

[0066] The housing rear extension portion 323 can extend rearward while enclosing the housing rear through-hole 322. That is, the housing rear extension portion 323 can guide the liquid to flow steadily into the housing main body 31.

[0067] The housing front part 33 is disposed in front of the housing main body part 31 and may communicate the inside and outside of the housing main body part 31, allowing the liquid that flows into the housing rear part 32 to flow out to the outside through the power part 1. Specifically, the housing front part 33 may include a housing front main body part 331, a housing front through-hole 332, and a housing front extension part 333.

[0068] The housing front body part 331 is coupled to the front of the housing body part 31 and can close the front surface of the housing body part 31. The housing front through-hole 332 is formed through the center of the housing front body part 331, and allows the liquid flowing inside the housing body part 31 to be heated by the power part 1 and to flow out by the rotational force of the power part 1.

[0069] The housing front extension portion (333) can extend forward while enclosing the housing front through-hole (332). That is, the housing front extension portion (333) can guide the liquid to flow steadily from the inside to the outside of the housing body portion (31).

[0070] The housing 3 may include an outer housing 3a and an inner housing 3b. The inner housing 3b may be disposed facing the power unit 1, and the outer housing 3a may be disposed spaced apart from the inner housing 3b in a shape corresponding to the outer housing 3a.

[0071] The outer housing (3a) and the inner housing (3b) are provided with a double structure, which can stably protect the power unit (1), stably heat the liquid flowing inside, minimize external influences, and maximize heating efficiency. The outer housing (3a) and the inner housing (3b) can each include a housing main body part (31), a housing rear part (32), and a housing front part (33).

[0072] Figure 3 is a perspective view of a heat pump according to an embodiment of the present invention. Figure 4 is a cross-sectional view of the heat pump shown in Figure 3. In describing various embodiments of the present invention with reference to Figures 3 to 20, redundant description will be omitted and modified or added components will be mainly described.

[0073] 3 and 4, a housing (3) according to one embodiment of the present invention may include a housing body portion (31), a housing inlet portion (34), a housing front portion (33), and a housing rear portion (32).

[0074] The housing body 31 may be provided to enclose the power unit 1. The housing inlet ports 34 are formed at intervals along the periphery of the housing body 31, and communicate the inside and outside of the housing body 31 to allow the inflow of liquid.

[0075] That is, the housing inlet (34) is located in the center of the housing body (31) so that liquid can flow in from the side of the housing (3). When the liquid flows toward the housing body (31), the flow resistance of the liquid is minimized, and the liquid can be easily heated and discharged.

[0076] The housing front part (33) is disposed in front of the housing main body part (31) and connects the inside and outside of the housing main body part (31), and can be configured so that liquid that flows into the housing inlet part (34) passes through the power part (1) and flows out to the outside.

[0077] Specifically, the housing front portion 33 may include a housing front coupling portion 334, a housing front extension portion 335, and a housing front adjustment portion 336. The housing front coupling portion 334 may be coupled to the housing main body portion 31.

[0078] The housing front extension portion (335) may be provided so as to extend at an angle from the housing front coupling portion (334) to the housing main body portion (31) and increase in cross-sectional area as it moves away from the housing front coupling portion (334). That is, the housing front extension portion (335) may reduce the velocity of the liquid heated by the power unit (1) and allow it to flow out at a large flow rate, thereby improving safety. The housing front adjustment portion (336) may be provided in front of the housing front extension portion (335) and may adjust the flow rate of the liquid flowing out. The housing rear portion (32) may be provided behind the housing main body portion (31) and may close the housing main body portion (31).

[0080] The outer housing (3a) and the inner housing (3b) have a double structure, which stably protects the power unit (1), stably heats the liquid flowing inside, minimizes external influences, and maximizes heating efficiency. The outer housing (3a) and the inner housing (3b) can each include a housing main body (31), a housing inlet (34), a housing front part (33), and a housing rear part (32).

[0082] 5 to 7, a rotating body 15 according to an embodiment of the present invention may include a rotating body 151, a rotating through-hole 153, a rotating outer shell 155, and rotating blades 157. The rotating body 151 may form the exterior.

[0083] The rotary through-hole 153 is formed through the center of the rotary body 151 and can be inserted into the shaft 13. The rotary through-hole 153 can accommodate the shaft 13 inside. The rotary through-hole 153 can be provided to correspond to the diameter of the shafts 13 that are connected in a multi-stage structure of multiple shafts 13. "Corresponding" can mean "the same."

[0084] The rotating outer shell 155 may be spaced apart from the rotating main body 151 and may be configured to surround the rotating main body 151. A plurality of rotating blades 157 may be provided between the rotating main body 151 and the rotating outer shell 155 to connect the rotating main body 151 and the rotating outer shell 155. That is, the rotating blades 157 may promote the flow of liquid by rotating. In other words, the liquid placed therein is heated by the polarity difference between the power unit 1 and the housing 3, and the heated liquid can be discharged to the outside by the rotation of the rotating blades 157.

[0085] The rotating blades (157) may be at least partially closed. That is, the rotating blades (157) may maximize the heat-generating area by completely closing the gaps between the rotating blades (157). The rotating blades (157) may also maximize the liquid circulation by completely opening the gaps between the rotating blades (157). In other words, the open area of ​​the rotating blades (157) may be set in consideration of the type of liquid, the number of rotating blades (157), the set temperature of the liquid, etc., thereby enabling efficient heating and improved circulation efficiency. Each of the first impeller (15a) and the second impeller (15b) may include a rotating main body portion (151), a rotating through portion (153), a rotating outer shell portion (155), and rotating blades (157).

[0086] 8 and 9 are views showing a heat pump including a housing partition according to an embodiment of the present invention, respectively.

[0087] 8 and 9, a heat pump (S) according to an embodiment of the present invention may include a partition (5). The partition (5) is provided on the housing (3) or the shaft (13) and can adjust the flow rate and speed of the liquid flowing inside the housing (3).

[0088] Specifically, the partition 5 may include a housing partition 51 and a shaft partition 53. The housing partition 51 is formed to protrude from the inner surface of the housing 3 and can adjust the flow rate of the liquid flowing inside the housing 3.

[0089] In addition, the housing partition wall 51 may be formed to protrude from the inner surface of the housing 3 so as to be disposed between the plurality of rotors 15. That is, the housing partition wall 51 may be formed to protrude from the inner surface of the housing 3 so as to be disposed between the first impeller 15a and the second impeller 15b.

[0090] Alternatively, the housing partition wall 51 may be applied with a first polarity or a second polarity, and the plurality of rotors 15 may be applied with a polarity different from that of the housing partition wall 51. That is, the housing partition wall 51 may be applied with a first polarity or a second polarity, and the first impeller 15a and the second impeller 15b may be applied with a polarity different from that of the housing partition wall 51, and the liquid may be heated by the polarity difference.

[0091] In addition, the housing partition (51) protrudes at its ends facing the first impeller (15a) and the second impeller (15b), thereby slowing the flow of liquid inside the housing (3) and maximizing the heating of the liquid.

[0092] A plurality of shaft partitions 53 are formed to protrude from the shaft 13 and can adjust the flow rate of the liquid flowing inside the housing 3. The shaft partitions 53 can be formed to protrude from the outer surface of the shaft 13 so as to be positioned between the plurality of rotors 15. That is, the shaft partitions 53 can be formed to protrude from the outer surface of the shaft 13 so as to be positioned between the first impeller 15a and the second impeller 15b.

[0093] Alternatively, the shaft partition wall 53 may be applied with a first polarity or a second polarity, and the plurality of rotors 15 may be applied with a polarity different from that of the shaft partition wall 53. That is, the shaft partition wall 53 may be applied with a first polarity or a second polarity, and the first impeller 15a and the second impeller 15b may be applied with a polarity different from that of the shaft partition wall 53, and the liquid may be heated by the polarity difference.

[0094] The shaft partition wall 53 may be provided so that its protruding height is smaller than the heights of the first impeller 15a and the second impeller 15b. This allows the shaft partition wall 53 to rotate together with the shaft 13, improving the flow rate of the liquid and increasing the heat circulation efficiency. The housing partition wall 51 and the shaft partition wall 53 may be provided separately or together.

[0095] 10 and 11 are views showing a heat pump including a housing slot and a shaft slot according to an embodiment of the present invention, respectively.

[0096] 10 and 11, a heat pump (S) according to an embodiment of the present invention may include a slot portion (7) that is provided in the housing (3) or the shaft (13) and allows the rotor (15) to be attached and detached.

[0097] The slot portion 7 may include a housing slot portion 71 and a shaft slot portion 73. The housing slot portion 71 is provided on the inner surface of the housing 3, and multiple rotating bodies 15 may be detachably mounted therein.

[0098] The housing slot 71 may be provided to surround the outer end of the rotor 15. That is, the outer end of the rotor 15 may be inserted into the housing slot 71 to couple with it, allowing for convenient adjustment of the number of rotors 15 coupled with the shaft 13. The housing slot 71 may be spaced apart from the outer end of the rotor 15 by a predetermined distance or may be in contact with the outer end of the rotor 15 to the extent that rotation is not impeded, allowing for easy rotation.

[0099] The shaft slot 73 is provided on the outer surface of the shaft 13 and can detachably accommodate multiple rotors 15. The shaft slot 73 can also be provided to surround the center of the rotor 15. That is, the shaft slot 73 can be inserted into the center of the rotor 15 for coupling, allowing for convenient adjustment of the number of rotors 15 coupled to the shaft 13. The shaft slot 73 can be spaced apart from the center of the rotor 15 by a predetermined distance or can be in contact with the center of the rotor 15 to the extent that rotation is not hindered, allowing for easy rotation.

[0100] The housing slots (71) and the shaft slots (73) can be provided separately or together to fix the rotor (15), thereby conveniently adjusting the heating degree of the liquid and the circulation speed of the liquid.

[0101] 12 is a cross-sectional view of a heat pump according to an embodiment of the present invention. Referring to FIG. 12, a housing 3 according to an embodiment of the present invention may include a housing body 31, a housing front part 33, a housing rear part 32, and a housing through-hole 35.

[0102] The housing main body (31) is configured to encase the power unit (1), the housing front part (33) can be arranged in front of the housing main body (31), and the housing rear part (32) can be arranged behind the housing main body (31).

[0103] A plurality of housing through-holes 35 are formed through the housing body 31 and the housing front portion 33, allowing liquid to flow in and out of the housing body 31. That is, the housing body 31, the housing front portion 33, and the housing rear portion 32 form a cylindrical shape, and a plurality of housing through-holes 35 are formed at intervals around the housing body 31 and in the housing front portion 33, thereby minimizing the overall volume of the heat pump S. In addition, liquid can easily flow into the housing body 31 through the housing through-holes 35 formed in the housing body 31, be efficiently heated by the power unit 1, and then easily flow out to the outside through the housing through-holes 35 formed in the housing front portion 33.

[0104] 13 is a view showing a heat pump including a housing recess according to an embodiment of the present invention. Referring to FIG. 13, the housing 3 according to an embodiment of the present invention may include a housing body 31, a housing recess 36, and a housing inlet 37.

[0105] The housing main body 31 can be provided to encase the power unit 1. The housing recess 36 can be formed by recessing the outer surface of the housing main body 31 toward the shaft 13.

[0106] A plurality of housing inlet holes 37 are formed through the housing body 31 and the housing recess 36, allowing liquid to flow in and out of the housing body 31. The housing inlet holes 37 may also be formed on one surface of the housing recess 36 facing the rotor 15.

[0107] Specifically, the housing recess 36 may be formed by recessing at least a portion of the side of the housing 3 facing the shaft 13. Also, the housing recess 36 may be applied with a power source of opposite polarity to that of the power unit 1 via the housing 3.

[0108] This allows the liquid to generate heat between the rotor (15) and the surface of the housing recess (36) facing the rotor (15) in the front-rear direction. Also, the liquid generates heat between the shaft (13) and the surface of the housing recess (36) facing the shaft (13) in the radial direction, thereby increasing the amount of heat generated by the heat pump (S).

[0109] As the position, length, width, shape, etc. of the housing recess (36) differs, the distance and area between the housing recess (36) and the rotor (15) and shaft (13), to which power supplies of different polarities are applied, change, and therefore, the heat generation amount of the heat pump (S) may differ depending on the shape of the housing recess (36), etc.

[0110] The housing inlet hole 37 can be formed on a surface of the housing recess 36 that faces the rotor 15 in the front-rear direction. As the rotor 15 rotates, liquid can flow into the housing 3 through the housing inlet hole 37 formed in the housing recess 36.

[0111] In addition, power supplies of opposite polarities are applied to the rotor 15 and the housing recess 36, respectively, so that heat can be generated in the liquid between the rotor 15 and the housing recess 36. As a result, the liquid flows into and out of the housing 3 through the housing inlet holes 37 formed in the housing recess 36, and vortexes are generated by the flow of liquid inside and outside the housing 3, and convection occurs due to the heat generated by the liquid inside the housing 3, thereby increasing the amount of liquid circulating inside and outside the housing 3.

[0112] 14 is a perspective view showing a heat pump with one side of the housing open according to an embodiment of the present invention. Referring to FIG. 14, the housing (3) according to an embodiment of the present invention includes a housing main body (31) and may optionally include either a housing front portion (33) or a housing rear portion (32).

[0113] That is, the housing body 31 is configured to enclose the power unit 1, the housing front portion 33 is disposed in front of the housing body 31, and the housing rear portion 32 is disposed behind the housing body 31. Since only one of the housing front portion 33 and the housing rear portion 32 is provided, the housing 3 can be open on either the surface facing the motor 11 in the front-rear direction or the surface facing the rotor 15 in the front-rear direction. Alternatively, the housing 3 may be provided with both the housing front portion 33 and the housing rear portion 32, with each portion being open to a certain extent. Alternatively, the housing 3 may not be provided with both the housing front portion 33 and the housing rear portion 32, and both sides may be open.

[0114] That is, the more the degree of opening of the housing 3 increases, the more the amount of liquid circulating in the housing 3. Therefore, the appropriate degree of opening and shape of the housing 3 can be selected in consideration of the desired amount of liquid circulating in the housing 3.

[0115] In addition, the rotor (15) can set the degree of opening between the multiple rotary blades (157) depending on the situation, and in this case, the degree of opening of each rotary blade (157) and the degree of opening of the housing (3) can be set by taking into consideration the degree of opening of the housing (3).

[0116] 15 is a view showing a heat pump including a housing extension according to an embodiment of the present invention. Referring to FIG. 15, the rotor (15) according to an embodiment of the present invention may include a rotating body (151), a rotating through-hole (153), a rotating outer shell (155), rotating blades (157), and a rotating support (159).

[0117] The rotating body 151 may have an outer periphery, and the rotating through-hole 153 may be formed through the center of the rotating body 151 and inserted onto the shaft 13. The rotating outer shell 155 may be spaced apart from the rotating body 151 and may be provided to surround the rotating body 151. A plurality of rotating blades 157 may be provided between the rotating body 151 and the rotating outer shell 155 to connect the rotating body 151 and the rotating outer shell 155. The rotation support 159 may be provided to surround the rotating through-hole 153 and may be formed to protrude from the center of the rotating body 151.

[0118] The housing 3 may include a housing main body 31, a housing front portion 33, a housing rear portion 32, and a housing extension portion 38. The housing main body 31 is configured to encase the power unit 1, the housing front portion 33 is disposed in front of the housing main body 31, and closes the housing main body 31, with the inner surface thereof facing the rotation support portion 159, and the housing rear portion 32 is disposed behind the housing main body 31, and can close the housing main body 31.

[0119] The housing extension portion (38) can extend from the inner surface of the housing front portion (33) toward the rotation through portion (153) and be disposed inside the rotation support portion (159). That is, the housing extension portion (38) can be configured to extend from the inner side of the surface of the housing (3) that faces the rotation support portion (159), receive power via the housing (3), and be inserted into the rotation support portion (159).

[0120] Specifically, the housing extension 38 extends from the housing 3 and receives power of the same polarity as the housing 3, and can be inserted so as to be spaced apart from the inner wall of the rotation support 159, to which power of the opposite polarity to the housing 3 is applied. As a result, when viewed from the radial direction of the rotor 15, the housing 3, the rotor 15, and the housing extension 38 are applied in this order, and a configuration in which power polarities are reversed is alternately arranged, thereby increasing the heat generation amount of the heat pump S.

[0121] In addition, the liquid located between the housing extension 38 and the inner wall of the rotation support 159 may generate additional heat by applying power of opposite polarity to the housing extension 38 and the rotation support 159. Therefore, the additional heat generated by the liquid between the housing extension 38 and the inner wall of the rotation support 159 may cause convection of the liquid located inside and outside the housing 3, thereby increasing the amount of liquid circulating inside and outside the housing 3.

[0122] 16 is a view showing a heat pump including a housing waterproof part according to an embodiment of the present invention. Referring to FIG. 16, the housing (3) according to an embodiment of the present invention may include a housing main body part (31), a housing front part (33), a housing rear part (32), and a housing waterproof part (39).

[0123] The housing body 31 is configured to enclose the power unit 1, the housing front part 33 is disposed in front of the housing body 31 and closes the housing body 31, and the housing rear part 32 is disposed behind the housing body 31 and can close the housing body 31. In addition, a plurality of housing through-holes 35 are formed in the housing body 31 and the housing front part 33, allowing liquid to flow in and out of the housing 3.

[0124] The waterproof housing part 39 is disposed inside the housing body part 31 so as to enclose the shaft 13, and may be provided to separate the motor 11 from the rotor 15 and to seal the motor 11. As described above, when viewed from the front-to-rear direction, the housing through-hole 35 may not be formed in the area of ​​the housing 3 where the motor 11 is provided, based on the waterproof housing part 39.

[0125] This prevents liquid from flowing into the space of the housing (3) that is sealed by the housing waterproof portion (39) and that houses the motor (11). This allows the use of a motor (11) that is not waterproof when constructing the heat pump (S), and allows other components that are vulnerable to moisture to be placed in that space, improving design flexibility and reducing manufacturing costs.

[0126] Figure 17 shows a heat pump having a double housing structure according to an embodiment of the present invention. Specifically, Figure 17(a) shows that a plurality of through holes are formed and spaced apart in the outer housing 3a, and Figure 17(b) shows that through holes are formed in the front and rear of the outer housing 3a.

[0127] 17, a housing 3 according to one embodiment of the present invention may include an outer housing 3a and an inner housing 3b. The inner housing 3b may be configured to house the power unit 1 therein. The outer housing 3a may be configured to house the inner housing 3b therein.

[0128] In addition, a space V through which a liquid can flow can be formed between the inner housing 3b and the outer housing 3a. At this time, the outer housing 3a can be configured so that no power is applied thereto. This reduces the wear rate of the outer housing 3a and prevents accidents such as electric shock or burns when a user touches the outer housing 3a.

[0129] 17(a) shows that the outer housing 3a has a plurality of housing through-holes 35 formed on the surface facing the inner housing 3b in the front-rear and radial directions. That is, the liquid in the space V can flow through the plurality of housing through-holes 35 formed in the outer housing 3a in the front-rear and radial directions, thereby increasing the flow rate of the liquid inside and outside the outer housing 3a.

[0130] 17(b) shows that the outer housing (3a) has at least one housing through-hole (35) formed on each of a pair of surfaces (front and rear) facing the inner housing (3b) in the front-rear direction. In other words, the liquid in the space (V) is surrounded by the inner housing (3b) and the outer housing (3a) in all directions except the front-rear direction, and the flow of the liquid inside and outside the outer housing (3a) can be concentrated in the front-rear direction.

[0131] Therefore, the flow of the liquid in the space (V) between the inner housing (3b) and the outer housing (3a) can have a relatively constant direction in the limited space (V). In other words, by measuring the flow rate and temperature of the liquid in the space (V), the performance of the heat pump (S) can be more easily measured.

[0132] 18A and 18B are diagrams showing a heat pump including a buffer member or a linear driver according to an embodiment of the present invention, in which Fig. 18A shows a heat pump including a linear driver and a buffer member, and Fig. 18B shows a heat pump including a linear driver.

[0133] The power unit 1 according to one embodiment of the present invention may include a linear drive unit 17. The linear drive unit 17 is provided inside the housing 3 and can move the motor 11, the shaft 13, and the rotor 15 in at least one of the forward and backward directions and the radial direction.

[0134] Specifically, the linear driving unit 17 may be supported on a surface of the housing 3 facing the motor 11 in the front-rear direction. In this case, the linear driving unit 17 may be configured in the form of at least one linear actuator configured to move the motor 11 in the front-rear direction. That is, one end of the linear driving unit 17 may be coupled to the surface of the housing 3 facing the motor 11 in the front-rear direction, and the other end of the linear driving unit 17 may be coupled to the motor 11.

[0135] The heat output of the heat pump (S) can be adjusted by moving the power unit (1) through the drive of the linear drive unit (17) and adjusting the distance between the housing (3) and the power unit (1). Thus, even if the installation position and installation angle of the heat pump (S) are changed at the installation location of the heat pump (S), the heat output of the heat pump (S) can be increased by moving the power unit (1) through the drive of the linear drive unit (17) to form an optimal distance between the housing (3) and the power unit (1) taking into account the changed installation position of the heat pump (S).

[0136] In addition, the movement of the power unit (1) via the linear drive unit (17) itself generates a flow of liquid inside and outside the housing (3), thereby improving the circulation of liquid inside and outside the housing (3). By utilizing this, even if the generation of rotational driving force via the rotor (15) of the power unit (1) is limited, the linear movement of the power unit (1) in the forward and backward directions via the linear drive unit (17) can cause the liquid inside and outside the housing (3) to flow, thereby minimizing the deterioration of the performance of the heat pump (S).

[0137] Meanwhile, the linear driving unit 17 may be supported on a surface of the housing 3 that faces the motor 11 in the radial direction. In this case, the linear driving unit 17 may be configured in the form of at least one linear actuator configured to move the motor 11 in the radial direction of the housing 3. That is, one end of the linear driving unit 17 may be coupled to a surface of the housing 3 that faces the motor 11 in the radial direction of the housing 3, and the other end of the linear driving unit 17 may be coupled to the motor 11.

[0138] In addition, the movement of the power unit (1) via the drive of the linear drive unit (17) itself generates a flow of liquid inside and outside the housing (3), thereby improving the circulation of liquid inside and outside the housing (3).

[0139] Furthermore, the heat pump (S) according to an embodiment of the present invention may include a buffer member (M). The buffer member (M) is installed inside the housing (3) to absorb shock. That is, the buffer member (M) may be installed at the corner of the surface of the housing (3) facing the rotor (15) in the front-rear direction.

[0140] In addition, the buffer member (M) can prevent the rotating body (15), shaft (13), and motor (11) from colliding with the housing (3) due to movement caused by the rotational driving force or vibration of the power unit (1), linear movement caused by driving the linear driving unit (17), etc.

[0141] The buffer member (M) is made of an elastic material such as rubber, and may be provided in the shape of a plurality of protruding polyhedrons as shown in FIG. 18(a), but is not limited to this.

[0142] 19A and 19B are diagrams showing a heat pump including an insulating part and a crank part according to an embodiment of the present invention. Specifically, FIG. 19A shows the crank part and the rotating insulating part, and FIG. 19B shows the crank part and the housing insulating part.

[0143] Referring to FIG. 19, a heat pump (S) according to an embodiment of the present invention includes a guide member (G) and a support member (H), and a power unit (1) may include a crank unit (18).

[0144] The guide member (G) can be configured to restrict radial movement of the housing (3) of the motor (11) and guide forward and backward movement of the motor (11). Specifically, the guide member (G) can be configured to have a length in the forward and backward direction corresponding to the range of forward and backward movement of the motor (11) driven by the crank portion (18), and to have at least a portion of the guide member (G) abut against the motor (11) in the radial direction, thereby restricting radial movement of the motor (11) and guiding forward and backward movement of the motor (11).

[0145] The support member (H) can be configured to support the guide member (G) in the radial direction of the housing 3. Specifically, one end of the support member (H) can be coupled to a surface of the housing 3 that faces the guide member (G) in the radial direction, and the other end can be coupled to the guide member (G).

[0146] The crank portion 18 may be configured to be supported on the inner surface of the housing 3 and to move the power unit 1 in the forward and backward directions. Specifically, the crank portion 18 may include a flywheel 181, a crankshaft 182, a crank arm 183, a connecting rod 184, and a coupling member 185.

[0147] The flywheel 181 stores rotational energy generated by the drive of the crank part 18, thereby preventing sudden speed fluctuations of the crank part 18. The crankshaft 182 is formed with an axis perpendicular to the front-rear direction and may be connected to a separate servo motor (not shown) to transmit power thereto and rotate. The crank arm 183 may be connected to the crankshaft 182 and rotate.

[0148] The connecting rod 184 may have one end connected to the crank arm 183 and the other end connected to the connecting member 185. That is, the connecting rod 184 rotates in connection with the crank arm 183, and transmits the power generated by the rotation of the crank arm 183 to the connecting member 185.

[0149] The connecting member 185 can be connected at one end to the connecting rod 184 and at the other end to the motor 11. In this case, the connecting member 185 can move the motor 11 forward and backward in response to the rotation of the crank arm 183.

[0150] That is, the crank portion (18) can adjust the distance between the housing (3) and the power unit (1) by moving the power unit (1) in the forward and backward directions, thereby adjusting the amount of heat generated by the heat pump (S).

[0151] Furthermore, the movement of the power unit (1) driven by the crank unit (18) itself generates a flow of liquid inside and outside the housing (3), thereby improving the circulation of liquid inside and outside the housing (3).

[0152] Meanwhile, the insulating portion 9 is provided on the housing 3 or the rotating body 15 and can suppress the flow of current. The insulating portion 9 can include a housing insulating portion 91 and a rotating insulating portion 93. The rotating insulating portion 93 can be provided on the rotating body 15 and can be made of an insulator to suppress the flow of current.

[0153] In addition, the rotating insulating portion (93) can be configured in the shape of a disk with a groove formed in the center so that the shafts (13) are spaced a predetermined distance apart in the radial direction of the shafts (13) and the housings (3) are spaced a predetermined distance apart in the radial direction of the housings (3).

[0154] That is, the rotating insulator 93 can be configured so that at least a portion thereof is coupled to the surface of the rotating body 15 that faces the motor 11. Therefore, when viewed from the front-to-rear direction, the liquid heated between the housing 3 and the rotating body 15, to which power supplies of different polarities are applied, can circulate mostly within the region of the housing 3 where the rotating body 15 is provided and outside the housing 3 adjacent to that region, with the rotating insulator 93 as the reference.

[0155] In other words, when viewed from the front-to-back direction, the heat generated by the heat pump (S) and the liquid circulation inside and outside the housing (3) can occur mostly in the area of ​​the housing (3) where the rotating body (15) is located, based on the rotating insulating part (93), and outside the housing (3) adjacent to that area.

[0156] In addition, when viewed from the front-to-rear direction, the motor (11), shaft (13), and crank portion (18) located in the area of ​​the housing (3) in which the motor (11) is installed based on the rotating insulating portion (93) may have a reduced rate of wear due to heated liquid inside the housing (3).

[0157] In addition, when the power unit 1 moves via the drive of the crank unit 18, the rotational insulator 93 connected to the rotor 15 moves, which may cause a liquid flow between the inside and outside of the housing 3. Therefore, the rotational insulator 93 can improve the liquid circulation between the inside and outside of the housing 3.

[0158] The housing insulating part 91 may be provided inside the housing 3 and may be made of an insulator to suppress the flow of current. The housing insulating part 91 may be spaced a predetermined distance from the shaft 13 in the radial direction of the shaft 13 and may be coupled to a surface of the housing 3 that faces the shaft 13 in the radial direction.

[0159] In other words, the housing insulating portion (91) can be positioned in the area of ​​the housing (3) in the direction where the motor (11) is provided relative to the rotating body (15) so that its end does not interfere with the range of movement of the rotating body (15) in the forward and backward directions when viewed from the front-to-back direction as the crank portion (18) is driven.

[0160] As a result, the liquid heated between the housing (3) and the rotating body (15), to which power supplies of different polarities are applied, can circulate, when viewed from the front-to-back direction, mostly within the area of ​​the housing (3) where the rotating body (15) is located and outside the adjacent housing (3), with the housing insulating portion (91) as the reference.

[0161] That is, when viewed from the front-to-rear direction, the heat generated by the heat pump (S) and the circulation of the liquid inside and outside the housing (3) can occur mostly in the area of ​​the housing (3) where the rotor (15) is located relative to the housing insulation part (91) and in the adjacent area outside the housing (3). Also, when viewed from the front-to-rear direction, the motor (11), shaft (13), and crank part (18) located in the area of ​​the housing (3) where the motor (11) is located relative to the housing insulation part (91) may experience a reduced rate of wear due to the heated liquid.

[0162] 20 is a view showing a heat pump including a blade control unit according to an embodiment of the present invention. A rotor (15) according to an embodiment of the present invention may include a blade control unit (158).

[0163] The blade control unit 158 ​​is installed inside the rotation support unit 159 and can adjust the angle and position of the rotating blade 157. If the blade control unit 158 ​​is installed, the rotating outer shell 155 may be omitted.

[0164] In addition, the blade control unit (158) can be configured to adjust at least one of the rotation angle of the rotating blade (157) relative to the radial direction of the rotation support unit (159) and the rotation angle of the rotating blade (157) relative to the side of the rotation support unit (159) that faces the inner surface of the housing (3) in the radial direction of the rotation support unit (159).

[0165] Specifically, the blade control unit 158 ​​may include a first blade control unit 158a and a second blade control unit 158b. The first blade control unit 158a may be configured in the form of a motor so as to rotate the rotating blades 157 in the radial direction of the rotation support unit 159. This allows the rotating blades 157 to rotate in the same direction as the motor rotation direction of the first blade control unit 158a.

[0166] That is, the blade control unit 158 ​​can adjust the rotation angle of the rotary blade 157 relative to the radial direction of the rotation support unit 159 by adjusting the motor rotation of the first blade control unit 158a. The second blade control unit 158b can include a guide rail 1581, a rail connecting member 1583, and a linear drive unit 1585.

[0167] The first blade control portion (158a) can be rotatably coupled to the rotation support portion (159) so as to be rotatable relative to the side of the rotation support portion (159) that faces the inner surface of the housing (3) in the radial direction of the rotation support portion (159).

[0168] That is, when an external force is applied to the first blade control part (158a) by the two-blade control part (158b), the first blade control part (158a) can rotate relative to the side of the rotation support part (159) facing the inner surface of the housing (3) in the radial direction of the rotation support part (159) while being connected to the rotation support part (159).

[0169] The guide rail 1581 can be coupled to the inner surface of the rotation support 159 along the radial direction of the rotation support 159. The rail coupling member 1583 can be configured such that one end is coupled to the linear drive unit 1585 and the other end is coupled to the guide rail 1581 so as to be movable along the guide rail 1581.

[0170] The linear driving device 1585 is configured in the form of a linear actuator and can be configured to be able to move linearly through extension and contraction. One end of the linear driving device 1585 is connected to the first blade control unit 158a and the other end is connected to the rail connecting member 1583. The linear driving device 1585 can be driven by a separate servo motor (not shown).

[0171] That is, when the linear driving device 1585 is extended, the rail connecting member 1583 can move in the radial direction of the rotation support part 159 along the guide rail 1581. Then, with the movement of the rail connecting member 1583, the linear driving device 1585 can rotate relative to the side of the rotation support part 159 that faces the inner surface of the housing 3 in the radial direction of the rotation support part 159. Furthermore, in response to the rotation of the linear driving device 1585, the first blade control part 158a connected to the linear driving device 1585 and the rotary blade 157 connected to the first blade control part 158a can rotate.

[0172] Alternatively, when the linear drive unit 1585 is retracted, the rail coupling member 1583 can move along the guide rail 1581 in the opposite direction to when the linear drive unit 1585 is extended, and the rotating blade 157 can rotate in the opposite direction to when the linear drive unit 1585 is extended.

[0173] That is, the blade control unit (158) can adjust the rotation angle of the rotating blade (157) relative to the side of the rotating support part (159) that faces the inner surface of the housing (3) in the radial direction of the rotating support part (159) by adjusting the extension and contraction of the linear drive device (1585).

[0174] In addition, the rotating blades (157) may be configured to have a curved shape that forms a curve in the radial direction of the rotation support part (159). As a result, when the rotation angle of the rotating blades (157) changes, the amount and direction of the liquid pushed out by the rotor (15) included in the heat pump (S) can change.

[0175] In addition, power supplies of opposite polarities may be applied to the rotating blades 157 and the housing 3. This allows the amount of heat generated by the heat pump S to change depending on the distance between the rotating blades 157 and the housing 3 and the area of ​​the area facing them. In this case, the rotating blades 157 may be configured in a curved shape by forming a curve with respect to the radial direction of the rotation support part 159. Since the radial direction of the rotation support part 159 is the same as the radial direction of the housing 3, the distance between the rotating blades 157 and the housing 3 and the area of ​​the area facing them can change when the rotation angle of the rotating blades 157 changes.

[0176] Thus, by adjusting the rotation angle of the rotary blades (157) via the blade control unit (158), the heat generation amount of the heat pump (S), the liquid flow rate, and the liquid flow direction can be adjusted.

[0177] Although the representative embodiments of the present invention have been described in detail above, it should be understood by those skilled in the art that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the following claims as well as equivalents to these claims.
